1 UNIVERSAL COAXIAL CABLE CONNECTOR This invention relates to coaxialcable connectors, and more particularly to connectors which can be usedwith cables of nominally the same diameter but which actually havedifferent outer diameters.

The function of a coaxial cable connector is to connect the inner andouter conductors of a coaxial cable to a standard output plug or jack.The standard output plugs and jacks can be of types TNC, N BNC, I-IN,LC, LT, SMA and UHF, and each can have a male or female configuration.Different connectors are required for different size cables. thusmultiplying the total number of possible connectors which may have to beused.

There are many requirements which must be satisfied by a coaxial cableconnector. It should be relatively simple to attach the connector to thecable and to make reliable electrical contact with both the inner andouter conductors. The connector, after it is attached, should remainlocked in place andno radiation should pass through it except along theinner and outer conductors. Furthermore, the connector should bewater-tight so that moisture on the cable outer conductor does not enterinto the body of the connector.

One of the major problems with prior art connectors relates to the factthat the actual outer diameters of the same nominal size cables ofdifferent manufacturers are not exactly equal. Nominal sizes of coaxialcables are A, V2, /8 and 1-% inches, but the actual outer diameters ofcables of the same nominal size mayvary by almost 10%. Furthervariations are encountered when corrugated and non-corrugated cables arecompared.

(The outer conductors of some cables are corrugated to make them moreflexible.) It is exceedingly difficult to provide a single connector ofa particular plug or jack type for a particular size cable which canactually be used with the cables of the different manufacturers. Forthis'reason, it is the industry practice to provide separate connectorsfor the same nominal size cable for use with the cables of differentmanufacturers. In actual practice, it is not only necessary for a userto stock many more connectors than would be thought necessary, but it isoften found that in the field the proper connector for a cable of aparticular manufacturer may not be availablesln such a case, ifaconnection is made using a wrong connector'it is often unsatisfactory.

It is a general object of our invention to provide a connector which canbe used to satisfaction with the cables of different manufacturers whichhave the same nominal size but whose actual outer diameters may vary.

In accordance with the principles of our invention we provide a slottedplastic sealing gland, of conical shape,

which is placed within an internal conical bore of a retaining nutplaced around the outer conductor of a coaxial cable. The body of theconnector, having a standard plug configuration at its forward end, canbe tightened around the retaining nut and includesa central contact forengaging the inner conductor of the cable. Within the body of theconnector, and disposed around the outer conductor of the cable, thereis a wire mesh ring separated by a washer from the sealing gland. As

the body is screwed on the retaining nut, the sealing gland and the wiremesh ring are forced toward each other.

As the connector is thus tightened, the sealing gland is forced into theconical bore of the retaining nut and is thereby tightly clamped aroundthe cable. The slots in the sealing gland allow it to bend inwardly andtightly grip a cable of any outer diameter within the range normallyassociated with the nominal cable size for which the connector isdesigned. The axial compression of the wire mesh ring causes itsinner'diameter to be shortened and its outer diameter to be lenghtened.It is the inner and outer expansion of the ring which insures that goodelectrical contact is made between the body of the connector and theouter conductor of the cable, and that a tight mechanical fit ismaintained between them. The wire mesh ring also provides complete radiofrequency interference shielding.

It is a feature of our invention to provide a compressible sealing glandwithin the retaining nut of a coaxial cable connector for allowing thesealing gland to make tight physical contact with the outer conductor ofa cable when it is forced into the retaining nut.

It is another feature of our invention to provide within the body of theconnector a wire mesh ring, disposed around the outer conductor of thecoaxial cable, which is capable of both inner and outer expansion whenit is compressed in the axial direction as the body of the connector isscrewed on the retaining nut.

Further objects, features andadvantages of our in vention will becomeapparent upon consideration of the following detailed description inconjunction with the drawing, in which:

FIG. 1 is a cross-sectional view of an illustrative embodiment of ourinvention;

FIG. 2 is a cross-sectional view of another illustrative embodiment ofour invention;

FIGS. 3A and 3B are cross-sectional and top views of element 28 of FIG.1; and

FIG. 4 is a cross-sectional view of element 42 of FIG.

Cable 10in FIG. 1 includes a conventional outer conductor 12 (of thesmooth type, although the connector 20 can be attached to a corrugatedcable of the same nominal diameter as well), a central conductor 14 anda layer of dielectric (not shown) which separates the inner andouterconductors. The end of the cable is cut so that the inner conductorextends out past the dielectric and the outer conductor.

The forward end of connector 20 has the standard female-type Nconfiguration. This configuration consists of an inner female contact 42with fingers 42a.

which is electrically connected to inner conductor 14 of the cable, andan outer body 22 which is electrically connected through variousconnector parts to be described below to outer conductor 12 of thecable.

Retaining nut 26 is provided with an outer screw thread 26a, and aconical bore 26b. Inner diameter 26c of the retaining nut surrounds thecable but may not make contact with it. The inner diameter 260 is atleast as large as the largest outer diameter of any cable of the nominalsize for which the connector 20 is to be used. Sealing gland 28, shownmost clearly in FIGS. 3A and 3B, is preferably made of nylon or Deldrin.The sealing gland is conical in shape so that it mates with the conicalbore 26b in the retaining nut. But the sealing gland includes a seriesof slots 28b around its periphery which define eight fingers 28a whichcan be bent inwardly. The smaller the outer diameter of a cable, thefarther that the sealing gland can be pushed into the bore of theretaining nut. The farther that the sealing gland is pushed into thebore, the greater the inward bend of fingers 28a. The tightening of theconnector forces the sealing gland into the conical bore of theretaining nut so that a very tight fit of the retaining nut-sealinggland combination can be had around the cable.

A rubber O-ring 30 is forced into seat 280 of the sealing gland when theconnector is tightened. The O-ring deforms to the cross-sectional shapeshown in FIG. 1 and provides a water-tight seal so that moisture on thecable, even if it gets under the sealing gland, cannot pass under theO-ring seal to get into the body of the connector.

Brass washer 32 is disposed between sealing gland 28 and wire mesh ring34. The function of the washer is to separate the wire mesh ring fromthe retaining nut 26 so that the wire mesh ring rotates as little aspossible when body 24 is turned to tighten the connector. This is toprevent tearing of the wire mesh ring.

Wire mesh ring 34 is a solid mesh, preferably made of Monel (stainlesssteel with an added amount of nickel). The material itself is much likethat of the washing pad sold under the mark Brillo. The function of thewire mesh ring will be described below.

Forward of the wire mesh ring is a metallic bushing 36 having a seat 36aagainst which the forward end of the cable bears. The seat of thebushing locates the cable along the central axis of the connector sothat inner conductor 14 is aligned with the axis of the connector. Thisfacilitates attachment of contact 42 to the inner conductor as will bedescribed below. The bushing also serves another function. Contact 42includes a plurality of fingers 42b which grip the exterior surface ofinner conductor 14. In effect, they increase the diameter of the innerconductor and this necessarily changes the characteristic impedance ofthe cable which typically may be 50 ohms. The bushing 36 provides anelectrical contact between the outer conductor 12 of the cable and thebody 24 of the connector. But the bushing, in so doing, providesinductive loading and functions as a matching ring. The configuration ofthe bushing, especially its seat 36a, insures that the characteristicimpedance of the cable-connector combination remains at 50 ohms despitethe fact that the outer diameter of the inner conductor is effectivelyincreased by fingers 42b of contact 42. Bushing 36 fits tightly withinbody 24 but since it can accommodate even the largest diameter cablewithin the nominal size range, perfect contact with the cable may not bepossible. As will be described below, the necessary reliable contact ismade by wire mesh ring 34 when the connector is tightened.

Body section 24 includes inner thread 24a which can be screwed on tothread 26b of the retaining nut 26. It is the turning of body section 24relative to the retaining nut that tightens the connector. Body section24 includes a seat 42d against which annular ridge 40a of insulator 40bears. The insulator fits tightly within body section 24, and serves toseparate contact 40 from the exterior conducting portion of theconnector.

Contact 42, shown most clearly in FIG. 4, includes inwardly bent tabs42a which define a female connector and a main shank having a straightknurl 42d for fitting tightly within the insulator 40. The rearward endof the contact includes a plurality of spring fingers 42b which arebiased inwardly; when the fingers are forced onto inner conductor 14,they form a reliable electrical connection between the inner conductorand contact 42. The contact includes a seat 42c which bears againstannular ridge 40b of the insulator. This is to insure that the contactcannot be pulled forward out of the connector. I

The remaining element of the connector is body portion 22 which includesinner thread 22a for engaging outer thread 24a of body portion 24.During manufacture of the connector, a liquid plastic such as that soldunder the mark Lock-Tite is placed between the threads. The plastichardens as it dries to lock the two body portions 22 and 24 to eachother, effectively forming a single body which can be screwed onto theretaining nut 26.

During manufacture of the connector, insulator 40 is first forced intobody section 24, and contact 42 is then forced into the insulator in adirection from right to left in FIG. 1. Thereafter, body section 22 isattached to body'section 24 as described above, and brass bushing 36 isforced into body section 24. All of these elements are permanentlysecured to each other. In order to ship the connector as a single unit,sealing gland 28, O-ring 30, washer 32, and wire mesh ring 34 can beplaced between retaining nut 26 and body section 24, and the bodysection can then be partially tightened around the retaining nut.

In order to attach the connector to a cable, the body is first screwedoff of the retaining nut. The retaining nut is placed on the end of thecable, the sealing gland is then pushed into the conical bore of thenut, and the O-ring is pushed into the seat 280 of the gland.Thereafter, washer 32 is placed over the cable followed by wire meshring 34. In the last step, the body, including contact 42, is pushedonto the end of the cable and rotated around the retaining nut. As theconnector is tightened, wire mesh ring 34 is forced to the right,pushing washer 32 along with it. The washer bears against the sealinggland and forces it deeper into the conical bore 26b. It is the forcingof the sealing gland into the conical bore that causes the fingers ofthe sealing gland to be bent inwardly to effect a secure grip with theouter conductor of the cable. At the same time, the axial compressionforces applied to the wire mesh ring cause its width to be reduced, itsinner diameter-to be shortened and its outer diameter to be lengthened.Consequently, the wire mesh ring not only acts as a lock between theouter conductor of the cable and body section 24 by reason of its beingin a state of compression, it also makes reliable electrical contactwith both the outer conductor of the cable and the body portion. Thewire mesh ring also provides the necessary radio frequency interferenceshielding expected of a connector by reason of the tight fit.

It is important to note that excessive tightening of the connector doesnot result in the wire mesh ring crushing the cable. In some prior artconnectors, excessive tightening of the connector can result in crimpingof the outer conductor. But because the wire mesh ring is resilient, ifthe connector is tightened too much, the wire mesh ring is simply placedunder increased compression rather than the inner diameter of the ringshrinking excessively so as to crush the cable.

It is of interest to note that the outer diameter of insulator 40 issmaller toward the forward end of the insulapart 24 is forward of thechange in the outer diameter of contact 42. The slight axial separationbetween the changes in diameter is due primarily for impedance matchingpurposes to insure that the characteristic impedance of theconnector-cable combination is the same as thatof the cable alone.

It is the combination of tapered gland 28 and wire mesh ring 34 whichallows the same connector to be used with the same nominal size cable ofdifferent manufacturers without making any sacrifice in quality. Tightmechanical fits and good electrical contacts are achieved because of thecompressibility and slideability of the sealing gland, and theexpansibility of the wire mesh ring when under axial compression.

FIG. 2 shows a similar type N connector 60, but having a male plug. Toconstruct such a connector, slightly different forward components mustbe incorporated in the unit. However, the rear portion of the connectoris the same as that of FIG. 1.

Body 22 of the connector of FIG. 1 is replaced by body 62. This elementincludes a cylindrical section 62b which is required in a male type-Nconnector. It also includes a circular groove 62a over which snap ring64 is placed. The snap ring is simply a ring having a radial slot in it.After the snap ring is fitted on the unit, a conventional moisturesealing washer 68 is placed over the cylindrical section 62b, followingwhich coupling nut 66 is forced over the snap ring. While the couplingnut serves a purely mechanical function, it is body portion 62 which isan extension of the cable outer conductor (as is body portion 22 in theconnector of FIG. 1). The male connector of FIG. 2includes a contact 70whose fingers 70b are comparable to fingers 42b of contact 42, but whoseforward end 70a comes to a point rather than being provided withinwardly bent tabs 42a. The only differences between the connectors ofFIGS. 1 and 2 are in their forward ends.

From a comparison of FIGS. 1 and 2 it will be apparent that male andfemale connectors of all types may be .constructed simply by providingforward elements of conventional shapes and central contact pins of therequired configurations, the rearward end of each pin having springfingers which may be securely attached to the inner cable conductorwithout even requiring a solder connection. Although a connector must bestocked for each nominal size cable for each standard type of plug, thesame connector can be used in all cases for cables of differentmanufacturers which are of the same nominal size. This is due to thefact that the tapered gland 28 can be forced into retaining nut 26 sothat its fingers 28a are bent inwardly to securely grip a cable whoseouter diameter may vary slightly, and wire mesh ring 34, when axiallycompressed, expands both inwardly and outwardly in the radial directionso as to establish a tight mechanical fit and a good electrical contactbetween body element 24 and the outer conductor of the cable.

While the invention has been described with reference to particularembodiments, it is to be understood that these embodiments are merelyillustrative of the application of the principles of the invention.Numerous modifications may be made therein and other arrangements may bedevised without departing from the spirit and scope of the invention.
